When using <code>Single-click</code> or <code>Click</code> you can hold do <code>Shift</code> key to toggle the feature in the selection.</p> <p>Note: when <code>Single-click</code> is used double-clicks won&#39;t select features. This in contrast to <code>Click</code>, where a double-click will both select the feature and zoom the map (because of the <code>DoubleClickZoom</code> interaction). Note that <code>Single-click</code> is less responsive than <code>Click</code> because of the delay it uses to detect double-clicks.</p> <p>In this example, a listener is registered for the Select interaction&#39;s <code>select</code> event in order to update the selection status above.</p>
